%gradient question...(12 posts)

%gradient question...bicycle268

Just got back from a hill climb session out in good ole' Morristown, NJ. Anyway, there's this really nice hill on Schoolhouse road that rises about 650 feet over approx. 2 miles. I usually get my arse kicked on climbs but I really do love the suffering. When I downloaded my ride today off my s720 I noticed that the grade % calculated to be 5.8%. Now I'm no flyweight but I have pretty good legs,a pretty good bike and '250 mile a week' fitness.
ok, now the question:
If 5.8% over 2 miles kicks my butt I couldn't imagine how 7% over 9 miles would be (in France). Or is my s720 messing with my mind?

FWIW- After the climb I recovered quickly and felt like doing it all again.....did I? No!!
5.8% sounds right, but how's about 12% over 7.6 miles @jiggs

Mount Washington (coming up SOON) with the last 100 yards at 22%.
BTW I might be wrong but divide the rise (650 ft) by the distance in feet (2 miles X 5280') and you get 6.1%
12% is scary for that length!! I hope you survive!!bicycle268

I have nothing but steep short hills in my immediate area. My driveway is 12% for about 300-400ft the road out of the nieghbor hood is 7% and then lef ton the main road its 6% then 8% for a short distance, I think only .5 miles. We dont have any long duration climbs locally. I will need to travel about 2 hours away to get any real climbs.

I actually took the topography of my neighborhood into consideration when looking for a house. I didn't want anything too severe to interrupt with my slow warm-up. After getting a mile from your house my legs would be screaming to go back home!!

Oh my, you'ld love my local hill climb. Next Sunday the 17th. Sea level to 10,000 ft. covering 36 miles. It's a great 3.5 hr interval ! Under 3 hours puts you into the "big dog" club.
Since I'm in Jersey...I checked it out...biknben

I use TopoUSA to search for and check gradients. Schoolhouse Lane in Morristown from the lowest point to the end is 1.91 miles and 598 feet of climbing. Your polar wasn't fibbing.

If and when you want to take things to the next level, there are many climbs around the Lebennon area off of Rte 22 and 78.

There are also some challenging ones North in Passaic Cnty (where I grew up). Skyline Drive off of Rte. 287 is popular. It provides a 9% avg. for a couple miles and peaks at 17%.

I did Mt. Washington last month. Having done that makes the stuff in Jersey just seem like rollers.
thanks for the input.bicycle268

I usually get out to southern passaic county a couple times a month and love the climbs through fayson lakes, kinnelon and out towards butler. I'll check out that Skyline drive ASAP

I'm curious - What's the grade of Mt. Tabor?Kristin
Aug 10, 2003 6:06 AM
I've heard lots of different figures for this climb. I've been told it was as low as 6% and as high as 20%. Getting conflicting figures like that about the climbs I've actually seen, makes it difficult to image what a particular grade is in threads like this. For instance, if Mt. Tabor is only 6%, then 22% would be like riding up the side of a building. Does anyone know the "real" grade of Mt. Tabor?

Also, can someone tell me what the steepest grade is along this stretch of County DL between Old Lake Road and Highway 113 in Baraboo, WI? Just curious. Thanks.

I only have TopoUSA for the NE region. Topozone.com couldn't find a Mt. Tabor. The link you provided wasn't working.

If you really want to know, measure the distance on your bike computer. Convert that distance to feet. Use TopoZone.com or some other topo map site to find the vertical rise. Rise (feet) / Distance (feet) x 100% = percent grade.

It's very possible that a climb could avg. 6% but have a short stretch at 22%. You may want to get the details from the person telling you how steep it is. In many cases, people describe a climb by using the STEEPEST part of the climb. That doesn't mean the entire climb is that bad. It's kinda like someone telling you they were cruising at 25 mph but they fail to mention the tailwind and the truck they were drafting. :-)
